The reaction between HCl and NaHCO3 will be; HCl + NaHCO3 = NaCl + CO2 + H2O The relative formula mass of NaHCO3 is 84 g/mol Moles of NaHCO3 in 2 g will be; 2/84 =0.0238 moles The mole ratio of HCl and NaHCO3 is 1;1 Thus, the number of moles of HCl is 0.0238 moles The volume of HCl will be; = 0.0238 moles/0.2 = 0.119 liters or 119 cm³
Energy may exist in different forms such as potential energy when a body is at rest, kinetic energy when the body is in motion, etc.
Energy can neither be created nor destroyed, however, it can be transformed from one form to another. For example, chemical energy may be transformed into mechanical energy or other forms of energy.
